WebFeb 5, 2024 · Abstract. Inositol-requiring enzyme type 1 (IRE1) is a serine/threonine kinase acting as one of three branches of the Unfolded Protein Response (UPR) signaling pathway, which is activated upon endoplasmic reticulum (ER) stress conditions. It is known to be capable of inducing both pro-survival and pro-apoptotic cellular responses, which are ...

WebFeb 4, 2024 · IRE1 is a transmembrane protein composed of three distinct domains, a sensing domain in the ER lumen, connected through a transmembrane segment to a cytosolic regulatory kinase domain, and finally a C-terminal RNase domain. WebMay 1, 2014 · RIDD is sequence specific. In S. cerevisiae, HAC1 mRNA splicing occurs by a nonconventional mechanism catalyzed by the coordinated action of IRE1 and the tRNA ligase RLG1 1, 2. The removal of the intron resembles that of pre-tRNA splicing, leaving free 2′,3′-cyclic phosphates.
